Abstract

In a multicard microprocessor system, when initial poweron diagnostic software fails to execute to an identifiable point of progress, the failing field-replaceable unit (FRU) cannot be directly determined. The "dead in the water" state causes replacement of many non-failing cards in an effort to find and replace the failing card.
